METALLIC BUFFER SPECIFICATION forming part BEAM EQUIPMENT.

of Letters Patent No. 643,828, dated February 20,1900.

T0 all whom it may concern.-

Be it known that I, HENRY H. SESSIONS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented a new and useful Improvement in Metallic Bufier-Beam Equipment,of which the following is a specification.

My invention relates particularly to an improvement in the metallicequipment of Wooden buffer-beams for passenger-cars; and my object is tosimplify'gre'atly the construction of such equipment as well as tostrengthen very materially the buffer-beam, the metallic equipmentitself,and the connections between said equipment and adjoining parts ofthe car.

Heretofore it has been the common method to form the head-block ordead-block, as it is as often termed, of wood and to equip said blockwith a metallic facing, with metallic sleeves or thimbles for thebuffer-stems, with a metallic name-plate, (functionally, also, afootboard,) and (in a vestibuled car) with metallic vestibule-postfoot-sockets,all of said metallic fittings being separately formed.

In my preferred construction all the several metallic parts enumerated,when present, are formed integrally and preferably of malleable lI'OIl.

In the accompanying drawings, which illustrate my invention in thepreferred form for use inconnection with-a vestibuled can-Figure 1 is abroken plan view, partly in section, of abufEer-beam and attendant partsequipped with my improvements, the section being taken as indicated atline 1 of Fig. 2; Fig. 2, a view in front elevation of the improvedmetallic equipment; Fig. 3, a view in rear elevation of the same; Fig.4, apartly-sectional plan view as indicated at line 4 of Fig. 2; andFigs. 5 to-S, inclusive, enlarged vertical sections at the correspondinglines of Fig. 1.

A represents the buffer-beam; B, its improved metallic equipment; C, thebufferplate; D, the diaphragm face-plate; E, the side bulfer-stems; E,the hinge-plates for pivotally securing the side buffer-stems to thebufier-plate; F,the center buffer-stem; G, the draft-beams of the steelsupporting structure of the car, and Ha vestibule-post.

The equipment B is preferably an integrally-formed malleable castingcomprising a dead-block B, aname-plate B and vestibulepost foot-socketsB The part 13 comprises a curved front face-plate a, having a largeradius of curvature, lower, center, and upper ribs a, a and arespectively, on the rear or concave surface of the plate a, sidebufferstem thimbles or sleeves a, and a center buffer-stem thimble a Theface-plate a is incurved or provided on its front surface with recessesat, to accommodate the side bufferstem fastenings E. The center rib a isprovided with a series of perforated bosses of, at which pointshorizontal tie-rods a and other securing-bolts (not shown) pass throughthe block. Vertical joint-bolts a and bolts a further secure the blockto the buffer-beam and the draft-beams. The upper rib a is preferablyinclined, as shown, and extends back of the main body of the block,where it is joined by a vertical web I) to the inner or back edge of thename-plate B The plate B is checkered or roughened over a portion of itsupper surface, and, as stated, serves the additional function of afoot-plate. The footplate I) of the spring-held bufier-head C movesbeneath the plate B in the usual manner. The space between the upper ribor top a of the dead-block proper and the plate B ,in fact, affords arecess for the plate I) of the bufferhead to enter when the latter isretracted. The ends of this space are partially closed by reinforcementsor fillings b beneath the footsockets B The buffer-beam is properlymortised to receive the thimbles a and a the extension of the top rib aand the web I), as clearly shown. If desired, the mortises may be madedeeper and the center andlower ribs mortised in also.

The above-described manner of forming the improved equipment renders itcomparatively light and permits it to be well malleableized. Changesinform and manner of manufacture, however, may be made without departurefrom myinvention. For instance, where the improvement is used with anon-vestibuled car the foot post-sockets are omitted and my inventionstill used with great advantage. Also, if desired, the equipment may beformed in two parts, the plane of division being indidicated by thedotted line 1 of Fig. 8.

It may be remarked that the dead-block herein claimed is to bedistinguished from the light metallic facing of the Wooden deadblockabove referred to and that the bufferstem thimbles with which theimproved deadblock is provided are to be distinguished from mereperforations in such a facing, it being essential that the stems beprovided with metallic sleeves of substantial length.

What I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a malleable cast-metal dead-blockfor buffer-beams having a curved face-plate and provided on 1ts innerside with projecting buffer-stem thimbles formed integrally therewithand adapted to-fit into sockets in the buffer-beam, substantially as andfor the purpose set forth.

2. As a new article of manufacture, a metallic dead-block forbuffer-beams provided with buffer-stem thimbles and a name and footplate formed integrally with said block,

substantially as and for the purpose set forth. 3. As a new article ofmanufacture, a me-. dead-block for buffer-beams provided tallic at itsupper portion with a rearward extension formed integrally therewith, andwhich, in turn, is provided with a forwardly-projecting foot-plate,substantially as and for the purpose set forth,

4. A metallic dead-block for buffer-beams, comprising a curvedface-plate, ribs integral therewith on the inner side thereof,bufferstem thimbles on the inner face of said plate and integraltherewith, an extension at the upper part, a web carried thereby, andafoot plate supported by and projecting forwardly from said web,substantially as and for the purpose set forth.

5. A malleable-iron dead-block provided with buffer-stem thimbles andfoot-plate formed integrally therewith, said block being recessed toreceive the coacting plate of the movable bu (fer-head, substantially asand for the purpose set forth.
